I absolutely love eucalyptus trees and we have some fantastic native species to choose from here in Australia so if you’re looking for a wonderful bush tucker tree, this may be the perfect pick for you. 

Introducing the Strawberry Gum Tree

Botanically referred to as Eucalyptus olida, common names now include strawberry gum, strawberry gum tree and forestberry. This species is part of the Myrtaceae family and is endemic to the restricted Northern Tablelands of New South Wales but is now being commonly cultivated in gardens across the country.

Though ideal for temperate regions, this tree can also be grown in subtropical conditions. Considered a slow to medium-growing species, forestberry trees will usually reach around 10 to 20 metres tall and 4 to 8 metres wide cultivated in suburban gardens. 

Safety First

  • This tree does have the potential to grow to 30 metres plus in optimal conditions so it may not be suitable for all suburban settings. 
  • It is best to plant this tree away from any buildings, paving, piping or other damageable properties. 
  • The leaves are also extremely rich in oils so they are highly combustible during bushfires.

How to Grow Strawberry Gum

Most professionals will recommend buying an established young and healthy nursery plant as many eucalyptus species are toxic and hybridization can also be toxic in landscapes. 

These tubestock plants will also be able to establish themselves faster and with more vigour so you can reap the benefits of the foliage sooner. 

Alternatively, the strawberry gum tree can be propagated from seeds sown in containers in early spring and then planted out in midsummer with little root disturbance. Seed-grown plants can take 5 years or more to establish themselves and start producing decent harvests.

Best Planting Conditions for Eucalyptus Olida

Propagating Strawberry Gum

Rosebank Growers

The most ideal time to plant this species is around March when temperatures are warm and stable. Many growers would suggest starting forestberry trees in large containers placed in sheltered positions in the garden.

They tend to perform well in pots for the first 1 to 2 years. You will need to move into larger containers as the roots begin to show. After this period, your tree should be ready for the garden bed.

Alternatively, nursery plants can be transplanted straight into the garden bed with some shelter during establishment as young plants need to be protected from cold winds and frosts. A plant or tree cover could help during this time.

See these plant cover bags available online as a reference.

Ideal Soil Conditions for Eucalyptus Olida

Moist and well-draining soils are ideal for forestberry. Loamy or clay-based soil types are also preferred. This tree enjoys a slightly acidic to neutral soil pH level of between 5 and 7.

Exposure

Full sun is recommended.

How to Care for Strawberry Gum Tree

Once established, this tree will be frost tolerant to -8°C but sensitive to drought. Here is how you can care for your strawberry gum tree.

Waterings

Daily watering will be required during hot dry weather. Overall, this species is thirsty and will appreciate regular watering. Water deeply and let the soil drain sufficiently if potted.

Allow the soil to dry out slightly before watering again. This is the case for both garden and pot-grown plants. Adding some seaweed solution to the water once a month or so can also encourage healthy growth. 

Pruning Needs

Regular, light pruning will help with maintaining a shorter tree and a denser canopy that is more suited for backyard environments. Pruning will be essential if you intend on keeping your forestberry smaller. 

Different types of plants call for distinct approaches so be sure to check out our guide to pruning Australian native plants for more info. 

Feeding

Fertilise with high-quality native plant food every 6 months to a year. 

Mulching

Add a thick layer of organic mulch around the base of the tree to prevent the soil from freezing and to encourage better soil moisture conservation. 

See our guide on the best types of mulch for the garden here.

Staking

It is important to grow your eucalyptus olida along a bamboo cane or similar tree stake to help condition it into an upright habit. If you intend on keeping the plant small and more shrub-like, staking won’t be necessary.
